Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The airline transport certificated pilot was conducting a 14 CFR Part 135 on-demand passenger flight in a tailwheel-equipped airplane. The pilot said he flew over the airstrip, and the wind sock indicated a strong right crosswind. As the airplane slowed during the landing roll, he said he lost rudder authority, and the airplane ground-looped to the right. He said the left wing received structural damage when it struck the runway following the collapse of the main landing gear. The pilot said there were no known mechanical anomalies with the airplane prior to the accident.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for a gusty crosswind, which resulted in a loss of control and an inadvertent ground-loop during the landing roll. Factors associated with the accident were the ground-loop and gusts.
